well yeah, that and the aesthetics of the "Lorinser" kit are non-existant. Nothing in the implementation or design is pleasant to look at.

Some people like the understated sleeper (stock) look.

oops, sorry, that lorinser s/c is on a CL500

I just noticed the Lorinser sc has a clutch. I wonder who's the manufacturer of the sc.

I agree that SLK is lighter and the 7 speed tranny shifts quicker but why did MBUSA.com list them both with the same 0-60 times? Are the 7 speed trannys on the 2005's or 06's.

Well I started this thread and the topic is STILL about Performance upgrading on blown AMG C55's. Since this is a C32, C55 forum would'nt you expect some C AMG owners to stand up for their models when you state for a fact that your model is faster than theirs? Should they just accept that without questioning your sources?

So you think I should be grateful? If you did try to insult me then you are truly an immature kid. Im sharing my experiences so that others who have not SC'd their cars can make informed decisions. Before you expect me to thank you for not insulting me why don't you try running your SLK55 against my pathetic HPS SC'd ride. My car may not be running perfect but I still dyno'd 406rwhp on STD standards yesterday. Just name a day and time. We can either do dyno or track. Your call buddy!

Gentlemen can we stick to the topic!

Okay so you agree SLK is lighter and 7 speed helps ... pretty much the same hp ... common sense would tell you which car would be faster. (and yes I know other factors like gearing etc) As to HP I've seen different numbers some the same as C55 some as you have posted. Yes I know MBUSA has your posted numbers. I do know I had a baseline of 299.78 HP SAE corrected. My baseline dyno is in the SLK thread.

2005 or 2006 for 7 speed. GO look it up ... I have a 2006 which does have a 7 speed. I didn't buy a 2005 so I don't care. Off the top of my head ... I'd have to guess that the 2005 does have the 7 speed.

"but why did MBUSA.com list them both with the same 0-60 times? "
are you one of those people that believe every written word? IF MBUSA writes 4.8 for both cars, then both cars MUST be 4.8?

"standing up for the C class" these are different cars, so if I said that a new E55 was faster than a C55 ... are you gonna argue as well? Thats like me arguing with a E55, SL65 etc.

"So you think I should be grateful? If you did try to insult me then you are truly an immature kid. " Honestly, I can't tell you how little your opinion means to me.

"Before you expect me to thank you for not insulting me why don't you try running your SLK55 against my pathetic HPS SC'd ride. My car may not be running perfect but I still dyno'd 406rwhp on STD standards yesterday. Just name a day and time. "
Did I say you had to thank me? nope I was expecting just basic courtesy. (Maybe your just on your period or something) I do have to say that your thread has been extremely helpful in making a decision for me. I've have decided NOT to go with HPS. Please let Adam know your thread lost them another customer. He might remember me since I talked with him a few weeks ago. (he even asked me to contact you as a reference) Now, when my car gets either Kleemann'd or REnntech'd in the next month or two I"ll take you up on your silly offer. I"ll name up here in Northern California ... I"m sure some other Kleemann cars(There are currently at least 2 SLK55 KLeemann up here) would love to come a real comparison between the various vendors and makes.

"We can either do dyno or track. Your call buddy!"
ROFL WTF dyno? You think doing a dyno fight off does anything? We can meet at a track with a 1/4 mile.

BTW this was about a stock SLK55 vs a stock C55. If you want, find someone with a stock C55 and we will run, before I get a kit, and we will see which is faster.

Obviously, the issues you have had modifying your car have given you a complex. I've never said before that your car was pathetic nor HPS's kit. I will say that the fact your having so many issues makes it BLATANTLY obvious that HPS has not done enough testing. As such, it would be silly for someone now to purchase one of thier kits. Even if they do completely fix your system most buyers would want to see that nothing happens to thier first "successful" kits over a period of time.

Was the lower price for the HPS kit worth all the BS you have had to go through? I'd say most of us probably would say that the time you have spent easily makes up for the additional costs of the Kleemann Kit or Renntech. I know your probably pretty upset about your whole ordeal, but don't be taking it out on others. You made your bed ... now sleep in it.

My apologies for the long post to all the other viewers here. I just had to vent a bit after reading how ridiculous this thread got at times.

"Gentlmen can we stick to the topic! "

Sorry about that ... my long *** post will be my last on this thread.

At least I had a source. Where's yours? MB is not biased since both models are theirs. Name a few articles please.

Not as much as you think. Their specs and performance are nearly identical. DragonAMG's car base dyno was 306rwhp SAE corrected. It's posted on this thread. Yours makes 299rwhp. Who's higher?

Read my post again. I just asked you where's your proof? What's so rude about that? Are you some delicate & sensitive little girlie?
I could care less. I don't work for HPS nor do I get a commission. Like I said before I tell it like it is Good or Bad. At least I can say I'm an honest consumer.

Great! That was my goal! To get more MB owners to SC their cars so we can have a little friendly competition. Win or Lose it's still more exciting than watching TV.

Just name the day. Loser pays for the track.

OK so are you calling out the C55 forum members here? I think you have at least a few in the bay area that will jump on that offer.

Uh... I think it would very wise to purchase one of their kits now because now it's proven and upgraded with ECU, Pulley Kit and custom injectors available to all future customers. But then again I just know that I got what I wanted and they got an improved kit. Worked out for both of us. BTW. They paid for my rental for every day it was in the shop. I actually saved miles on my car because I commute 70 miles a day in congested traffic.

Actually I'm pretty satisfied right now. I've always had a place in my heart for start-up companies and believe that's what America is all about! Competition and Risk-Taking.

AMGSC you ask about correction factors. Most tuners use SAE correction factor. If you decide to use STD that's ok but people will doc off about 10 hp from your graph, it's really your decision.

About the Dyno day, "Run what you brung and hope you brought enough". As it looks alot of heavy hitters in the MBZ community are coming out for this. If you think that 100, or C116 is gonna help your numbers than my advice to you is fill the whole tank up. Once your strapped down your getting 3 back to back pulls no cooldowns, the best of the 3 is your bragging rights.

AMGSC your car can be run in third gear with no downshift. Remember your car did it on my dyno, no problems. My car, Josh K's car,Mario's car, and Sohail's car all boosted ran in third gear. When you come over on the 15th I'll show you how it's done providing the TCM has not been hacked into.

Lynh, don't try throwing dirt on me. I know and you know that your brown nosing Adam and Jesse. Remember I'm the one who found the problem with these systems, and even told the owner how to rectify it. Now after listening to my advice HPS has finally made "some" improvements in the right direction. It's about damn time. I bet it's nice to know that you soon will be able to drive your car with the power you where promised right? Maybe I should of kept my mouth shut then none of this would of happened

You must be kidding!!!!! Proven???? By whom?????

Just because you think that your car is tuned properly, others should trust HPS that their kits will be OK???????

You have not even driven your car yet, you have no idea about idle quality, part throttle driveability, fuel economy or any other everyday "feel" that separates AMG from others.

Just because your C55 finally makes 400 rwhp and AFR is supoposedly 11.5 - therefore your car is tuned????

Sorry, but it is a lot more complex than that. I am willing to bet that this ordeal, unless you dump HPS, will be ongoing six months from now if not longer.

You are asking for our advice and we are willingly giving it to you, except you do not listen. You have a lot to learn on what it takes to tune a car to 100% factory feel.

Go drive E55K and get a feel for it. This is how your car should feel, this is how Kleemann cars feel.

I wish you lots of luck my friend!

You may be right because I just drove my car home from work yesterday and it's probably too early to tell.

But this time the check engine light did not come on and I drove it hard as I floored it at every stop light and punched it as I weaved in and out of traffic (Sorry Cops!). It really felt at least twice as strong as before. It still had a momentary stutter once or twice when I stomped on it but I think that's because the Exhaust can't keep up or the Tranny is slipping.I need to check that out with HPS.

The saga is not over yet because I am still trying to hit the mark that Jim said my car had which is 450rwhp because he is convinced that I'm losing 50rwhp in the drivetrain. They were thinking of bringing the car to a DynoPack machine where they actually remove the tires but I don't think it would help much. The Mustang Dyno was another suggested option. Several forum members told me that their cars had the same downshifting problem on MT's dyno but not on other Dynojets. I may just go to another Dynoject center on Monday to find out if this problem recurs.

As for the other drivability signs....It idles low at around 500rpm, motor sounds smooth during idling, excelerating in Park was even so far. But the most amazing thing is that I continue to get an average MPG of 28! on the freeway. The lowest MPG in local stop and go traffic was 17.4. I really can't complain about the mileage even with these massive injectors.

I would REALLY like to test drive a Kleemann, Renntech, Brabus or even Carlsson SC'd C55 for comparison. Do you know where I can do that here in Southern California?

I'm not sure where you are in LA but it would be nice to comapre your car with my C55R (RENNtech) I promise to leave the NOS tank out
That out give you a good feel for what a tuned S/C C55 feels like.
I am leaving town tomorrow night for 12 days. I will be at the meet on the 4th. If you are around tomorrow night, let me know. (assuming that the roads are dry) I live in Sherman Oaks.

Won't that blow your engine? Is it really safe? I might want to do that IF it's safe.

Didn't you post your problems on this forum not too long ago. I remember reading about it. So how did you resolve them?

When you get back then. Too short a notice. Got plans tomorrow but would love to meet up with you. SuperC55 would also be interested in meeting you I'm sure. He's also from LA. Can you get a hold of a Kleemannized C55 owner from LA and we can do a couple of test runs together? I should have my headers, cats and exhaust in by that time. Don't know about the cams yet.

It's like Vadim said, its all in the tuning. It is set to run with NOS - the A/F mixture.

Yes, I had issues after addding the headers, cams and the new programming. RENNtech came out and the owner personally fixed the car.

I have had alomst everything possible done to my C55R - except maybe having the catalytic converter taken out (Part of the Kleemann headers package; but since we live in LA Hartmut will not do it - and that is 20 hp right there) And I had a reputable company do it.
Hartmut (owner of RENNtech's owner) own words to me were:
"If it's not fast enought go buy another car! there is nothing else I can do!"
and i believe him, cause the car is FAST!
I guess we'll see each other at the meet.
I'll run with anyone!

Too Bad DragonAMG sold his car. I've been waiting like everybody else for the showdown. Now that he's sold his car (which is the only proven C55 so far) you are sounding pretty brash. But I understand. Owning a fast car can get your adrenaline pumping easy.

If you don't change the cats the power from the Headers would be nullified. Plus your stock cats will get real hot from burning off the excess exhaust and shorten its life. I got this fact straight from Jim at Mech Tech. He's done hundreds of header packages and swears that if you don't change the stock cats then you gain little if any extra power. I suggest you find a tuner that will install high-flow cats that is carb approved in LA.

AMGSC: Dude, please do not repeat someone elses opinions as facts. Especially opinions from Mechtech.

Jim is wrong. On many cars headers add power.

Headers on C32 (+20HP) and E55K (+30HP) add power without removing factory cats. We have done numerous before and after dynos.

And there are no CARB approved cats. Federal law prohibits removal of factory converters for 80,000 miles.

But Jim said...............

I agree w/most of everything you said Vadim, but why/how does KLeemann remove the primary cats w/their header package??

I'm not trying to start any wars here just trying to gain a little knowledge

We all know you are a trouble starter.
I bet you can't wait to get your car done, hopefully next week. I just put my blower back on and the car seems much quicker. Magnason replaced all the bearings, shaft and rotor. I'm guessing I got another pound of boost and it doesn't sound lilke a "rock tumbler" any more. I hope this is the last time. That was the third time my Maggie has been rebuilt in the last 8000 miles. Make sure you let me know when you go downt to the O.C. We can get some fellow MB members, grab some lunch and race back home

I just wanted to check with you about the EvoSport pulleys. I'm currently using them with my HPS supercharger. I was wondering if the pulleys affect the RPM's of the blower in anyway? I would say no, but HPS has said yes, but first they said it spins the blower too fast and then they said it will slow the blower down. To me I don't see why it would change anything on the supercharger.

Sorry if I come accross a little crass. I am just getting tired of repeating myself and dealing with half-truth.

Kleemann does not remove the primary cats, they relocate them about 4'' further down to get more space for a better collector. It requires cutting and welding to get them installed.

Another indication of HPSs lack of knowledge. Evosport Underdrive pulleys do not replace crankshaft pulley. They are larger power steering, alternator and water pump pulleys. They have no effect on blower RPM. You do not need to worry about them.

I got a tip from Richard023 that I should upgrade the SC water and fuel pumps on the HPS unit. What capacity water and fuel pumps do the Kleemanns, Renntechs, Brabus or Carlsson's use? Just curious.

Has anyone installed boost gauges, fuel pressure gauges and AFR meters on their SC'd rides? I know that the boost gauge is important if you are running on 7.5-8lbs of boost but what about AFR and fuel pressure gauges. I'm having these installed next week but I don't if I should go through with it if they don't add any real value.

I'll be installing boost and fuel pressure gauges on my A pillar. FYI, the A/F ratio gauge is little more than a lightshow unless you buy a wideband gauge. They're about 400 bucks though.
